Gatwick Express Class 387 at Hornsey

[Class455]

Morning all, just went past Hornsey Depot and noticed that there was a Gatwick Express Class 387 behind a small locomotive there. Any idea what unit it was and what it was doing there? Thought maintenance could be done at Selhurst or Stewart’s Lane

Hornsey frequently receives ‘guest’ units, typically for use of the wheel lathe.
